Step 1

Position racks in the upper and lower thirds of the oven; preheat to 450 degrees F. Halve the pork tenderloin crosswise, then halve lengthwise. Rub two-thirds of the garlic into the meat along with 1 teaspoon each oregano and cumin and a generous pinch each of salt and pepper. Set aside 10 minutes.

Step 2

Toss the sweet potato and broccoli in a large bowl with 1 tablespoon olive oil, the remaining 1/4 teaspoon cumin, 1/2 teaspoon salt and a few grinds of pepper. Spread in a single layer on a baking sheet and roast on the upper oven rack, stirring once, until lightly browned and tender, about 25 minutes. Meanwhile, cook the quinoa as the label directs.

Step 3

While the vegetables and quinoa cook, heat 1 tablespoon olive oil in a large ovenproof skillet over medium-high heat. Add the pork and cook until browned, about 5 minutes. Flip the pork and transfer the skillet to the lower oven rack. Roast until a thermometer inserted into the center registers 140 degrees F to 145 degrees F, about 5 minutes. Transfer to a cutting board.

Step 4

Stir the orange juice, vinegar, red pepper flakes, remaining garlic, 1 tablespoon olive oil and 1/4 teaspoon oregano in a small bowl; season with salt and pepper. Divide the quinoa and vegetables among bowls. Slice the pork and add to the bowls. Drizzle with the orange sauce.
